It is inserted toward 2b. At this time, the distal end portion of the core metal portion 121 relatively moves along the insertion hole 111 of the ear hook member 110 from the proximal end side 2a of the ear hook member 110 toward the distal end portion side 2b. One convex locking part 122 shifts to the other concave engaging part 112 in the ear hook member 110, where it is engaged and locked into the other concave engaging part 112. Thereby, the ear hook member 110 is held by the core metal member 120, and thus the ear hook member 120 can be easily attached to the core metal member 121. Further, when the ear hook member 110 is removed from the core metal member 120, the core metal portion 121 of the core metal member 120 inserted into the insertion hole 111 of the ear hook member 110 is on the proximal end side through the opening 111a. It is pulled out toward 2a. At this time, the engagement between the one convex locking portion 122 in the core metal portion 121 and the other concave engagement portion 112 in the ear hook member 110 is released, and the tip portion of the core metal portion 121 is moved to the ear hook member 110. It moves relatively along the insertion hole 111 of the ear hook member 110 from the distal end side 2b to the base end side 2a, and is separated from the base end portion 110a of the ear hook member 110. Thus, the ear hook member 110 can be easily detached from the core bar member 120.

  Thus, according to the temple 2 for eyeglass frames, the ear hooking member 110 constituting the temple 2 can be easily attached to and detached from the cored bar member 120 also constituting the temple 2, so that the user himself / herself can hook the ear hook. The member 110 can be replaced, and therefore, the entire temple need not be replaced, so that the cost can be reduced accordingly. Thereby, the burden on the spectacles user accompanying the replacement work is small, and the user himself can perform replacement easily and inexpensively.

  Further, the base end portion 110a of the ear hook member 110 is cut obliquely so that the engagement portion forming surface P1 of the insertion hole 111 where the other concave engagement portion 112 is to be formed is exposed, and the exposed engagement portion Since the other concave engagement portion 112 is formed on the formation exposed surface P1 ′, the other concave engagement portion 112 can be formed on the engagement portion formation exposure surface P1 ′ relatively easily and easily.

In some cases, it is provided so as to be recessed with respect to the engaging portion forming surface of the insertion hole 111, and in the case of a convex shape, it is provided so as to protrude with respect to the engaging portion forming surface of the insertion hole 111. When the other engaging portion 112 is formed, the other engaging portion 112 can be formed at an arbitrary position of the insertion hole 111 in the ear hook member 110.

  In addition, as shown in FIG. 6, when a plurality of pairs of concave and convex engaging portions 130 are provided along the axial direction, the cored bar portion 121 in the cored bar member 120 is inserted into the insertion hole 111 in the ear hook member 110. When one of the hooks 122 on the metal core 121 is engaged with the other concave engagement part 112 of the hook member 110 at a position that matches the distance between the user's nose and ear. Thereby, it can adjust favorably according to the distance between a user's nose part and an ear | edge part.

  In this example, the temple 2 is configured as a so-called plastic temple type, and the ear hook member 110 is detachable from the cored bar member 120, but is configured as a so-called metal temple type. In addition, an ear hook member and a cored bar member constituting the tip cell may be provided, and the tip cell may be detachable from the cored bar member.

  As described above, in the temple 2, the user can easily replace the ear hook member. However, as shown in FIG. 7A, the thickness of the ear hook member is increased so that the external force caused by the user's opening / closing operation or the like can be reduced. The ear hook member 110x with improved durability can be replaced, or as shown in FIG. 7B, a favorite ear hook selected from various decorated temples prepared in accordance with the TPO. The member 110y can be easily replaced.

  Further, the ear hooking member 110 in the temple 2 may be provided with an ear pad member 43 as shown in FIG. FIG. 8 is an enlarged schematic side view of an example of the tip 2b portion of the temple 2 shown in FIG. 1 in which the ear pad member 43 is provided at the tip 2b portion of the ear hook member 110. As shown in FIG. The temple 2 shown in FIG. 8 is the same as the temple 2 shown in FIGS. 1 to 6 except that in the temple 2 shown in FIGS. belongs to.

  As shown in FIG. 8, an ear pad member 43 capable of contacting the back side of the ear is detachably provided on the distal end side 2 b of the ear hook member 110. More specifically, the ear hooking member 110 is provided with a pair of left and right support portions 44 extending to the ear contact side at both ends in the width direction of the ear contact side portion. Screw holes 44a for fixing the ear pad member 43 with screws 8 are formed.

  The ear rest member 43 is provided with an extending portion 43 a that extends from the opposite side to the ear contact side in the substantially central portion in the axial direction Z. The extending portion 43a is formed with a through hole through which the screw 8 passes. Thereby, the ear pad member 43 can be detachably fixed to the ear hook member 110 by attaching the screw 8 to the screw hole 44a of the support portion 44 through the through hole of the extending portion 43a.

  Moreover, in the temple 2, as the ear hook member 110 applicable when performing intense exercise such as sports, for example, an ear hook member as shown in FIG. 9 and an ear hook member as shown in FIG. 10 can be easily replaced. Can do. The temple 2 shown in FIG. 9 is the same as the temple 2 shown in FIGS. 1 to 6 except that in the temple 2 shown in FIGS. 1 to 6, the ear hooking member 110 is provided with an ear pad member 23. The temple 2 shown in FIG. 10B is the same as the temple 2 shown in FIG. 1 to FIG. 6 except that the eyeglass attachment 30 is provided on the ear hooking member 110. This is the same as the temple 2 shown in FIG.

  The temple 2 shown in FIG. 9 has an ear contact portion 23a that can contact the back side of the ear and a shaft member 7 such as a pin or a screw for swingably attaching the rear portion of the temple body and the ear contact portion 23a. And a base end portion of the ear contact portion 23a and a predetermined portion 22b on the proximal end side 2a with respect to the portion 22a of the temple body to which the ear contact member 23 is attached. And a flexible entanglement preventing member 4 for connecting the side 2a end region 23c. In the illustrated example, the ear contact portion 23a, the predetermined portion 22b, and the entanglement preventing member 4 are integrally formed.

  In the eyeglass frame to which the temple 2 is attached, the nose pad 6 (see FIG. 1) attached to the front frame 1 is hung on the nose and the ear contact portion 23a of the curved ear pad member 23 is placed on the ear. It is worn by hanging on the curved part of the back side (between ear and head).

  In this spectacle frame, if the front frame 1 is about to slip off while wearing spectacles, the rear part of the temple 2 extending from the front frame 1 tends to slip out, and the ear attached to the rear part of the temple body. An attempt is made to move the ear contact portion 23a of the abutting member 23 upward. Then, when the ear contact part 23a of the ear pad member 23 tries to move upward, the swinging part 23b (the part 22a to which the ear pad member 23 of the temple body is attached) which is a part attached to the temple body of the ear pad member 23. 9), the ear contact portion 23a tends to rotate counterclockwise in FIG. At this time, the force with which the proximal end side 2a end region 23c of the ear contact portion 23a presses the back side of the ear increases, and as a result, the relative movement between the ear contact portion 23a and the back side of the ear is prevented. Thus, the rearward movement of the temple 2 is prevented. In this way, it is possible to prevent the glasses from slipping off.

  Further, the swinging portion 23b is provided at a substantially intermediate portion in the longitudinal direction of the ear abutting portion 23a, and the swinging portion 23b and the temple body, which are parts attached to the temple body of the ear pad member 23, are configured. The part 22a to which the ear pad member 23 is attached is configured to be provided with a restriction mechanism 18 that restricts the swing range of the swing part 23b, and between the temple body and the swing part 23b of the ear pad member 23. For attachment, a shaft member 7 such as a pin or a screw is used. The restricting mechanism 18 is configured to restrict swinging by the support piece 38 of the ear pad 23 coming into contact with the contact surface 28 provided on the portion 22a to which the ear pad member of the temple body is attached.

  By providing such a regulation mechanism 18, the swing range of the ear pad member 23 is restricted. Therefore, when the user puts on spectacles, the ear contact part 23 a of the ear pad member 23 is placed at an appropriate position on the back side of the ear. Can be easily brought into contact with each other, and the user can wear the glasses more easily. Further, since the ear rest member 23 is attached to the temple body attachment portion 22a via the shaft member 7, there is little loss of force, and smooth swinging can be achieved easily and inexpensively. Further, by providing the restriction mechanism 18 around the shaft of the shaft member 7, the restriction mechanism 18 can be easily configured. In addition, although the rocking | swiveling part 23b attached to the ear pad member 23 is attached to the shaft member 7 so that rocking is possible, a hole is made in the ear pad member 23 itself (ear contact part 23a), and the shaft member 7 is attached. The ear pad 23 may be attached to the temple body so as to be swingable. Further, the portion 22 a to which the ear pad member 23 of the temple body is attached is configured to be the distal end portion of the temple 2. In this case, even if the user has used a spectacle frame having a general shape, the temple 2 of the spectacle frame and the ear support member 23 are not integrated with each other. be able to.

  Further, as shown in FIG. 9, the flexible tangle prevention member 4 has a predetermined portion 22b located on the proximal side 2a from the portion 22a to which the ear rest member 23 of the temple body is attached and the ear rest of the ear rest member 23. It attaches so that the base end part 2a end part area | region 23c of the contact part 23a may be connected. By doing so, even when the temple 2 is lifted upward when removing the glasses, the entanglement preventing member 4 is formed between the temple body and the proximal end side 2a end region 23c of the ear contact portion 23a. Therefore, it is difficult for the hair to enter the attachment portion (swinging portion 23b) between the temple main body and the ear contact portion 23a from the Q direction, and the entanglement thereof is suppressed. Further, since the entanglement preventing member 4 has flexibility, it does not hinder the function of suppressing the omission of the spectacle frame. In this way, the predetermined portion 22b located on the proximal end side 2a from the portion 22a where the ear pad member 23 of the temple body is attached by the flexible entanglement preventing member 4, and the proximal end side 2a end of the ear contact portion 23a By connecting with the partial region 23c, it is possible to prevent the glasses from slipping without increasing the burden on the nose, and to prevent the hair from getting entangled with the glasses when the glasses are removed.

  The temple 2 shown in FIG. 10 includes a spectacle attachment 30. The eyeglass attachment 30 is an eyeglass attachment that can be attached to and detached from the eyeglass frame. The eyeglass attachment 30 can be attached to the distal end side 2b of the temple 2 as shown in FIG. It includes a contactable ear contact portion 30a, and a swinging portion 30b to which a shaft member 7 such as a pin or screw for swingably mounting the clip portion 30d and the ear contact portion 30a is mounted. is there. Further, the clip portion 30d and the ear contact portion 30a are attached to be swingable by a swinging portion 30b using a shaft member 7 such as a pin or a screw. Thereby, the temple 2 and the ear | edge contact part 30a of the spectacles attachment tool 30 are attached so that rocking | fluctuation is possible. Further, in the case where the temple 2 is gradually thickened toward the distal end portion, the clip portion 30d is prevented from falling off from the distal end side 2b of the temple 2 even if a predetermined margin is provided for the inner diameter of the clip portion 30d. can do.

  As shown in FIG. 10, one end is connected to the proximal end 2a end 30c of the ear contact portion 30a, and the other end is connected to the proximal end 2a from the portion 20a where the clip portion 30d of the temple 2 is attached. Further, a flexible entanglement preventing member 4 that can be attached to and detached from the predetermined portion 20b is further provided. A predetermined portion 20b on the proximal end side 2a from the portion 20a to which the clip portion 30d of the temple 2 is attached by the flexible entanglement preventing member 4 and the proximal end side 2a of the ear contact portion 30a of the eyeglass attachment 30 By connecting the end 30c, it is possible to prevent the glasses from slipping off without increasing the load on the nose, and to prevent the hair from getting entangled with the glasses when the glasses are removed.
